When attempting to spot emos or goths out in the wild, your best bet is to try dark and dingy days, preferably with a decent amount of fog or some light rain.
 
If you are successful in your endeavours, keep your distance. Though they may look empty and hollow on the outside, they are notoriously insular and skittish individuals. Although yes, they are in actuality hollow on the inside as well.
 
A common misconception is that they are merely in need of some kind of affection, often in the form of romantic partners. But be aware, a relationship with one is not something to be taken lightly, and hitting on one such girl in the street is liable to get you either a black eye or an all-consuming black-clad hole in your social life. You have been warned.
 
This is genuinely pretty, btw.
